An uncredentialed preparer may be experienced and capable. The challenge for a consumer is that qualifications can be harder to evaluate independently.
Ask more questions, not fewer
If a preparer does not hold a recognized professional credential, ask about formal tax education, continuing education, years in practice, types of returns prepared, review procedures, and who is available if a dispute or notice arises.
Representation can matter later
The person who prepares a return may not have the same ability to represent you before the IRS as an Enrolled Agent, CPA, or attorney. That distinction may not seem important on filing day, but it can become important if the return is later questioned.
Look for independent signals
Consider professional affiliations, verified education, disciplinary history where available, secure business practices, and references to authoritative tax sources. Do not rely solely on advertising claims or years-in-business statements.
When qualified credentialed tax professionals are available, it is reasonable to ask what advantage you gain by choosing someone whose qualifications are harder to verify.
